Why can't I load other models from the Roboflow OBS gesture controller tutorial?

I have watched the tutorial you posted on YouTube on how to switch images in OBS through gestures. I have tried it and it’s great, but I have a question. Why can’t I only load the OBS-3 model mentioned in the tutorial? For example, if I want to add another gesture model (Stone Scissor Cloth), it will always display in the loaded model and it won’t work. What is the reason for this?
